rax-scrollview: view will flash when user scroll and call scrollTo method with param animated: true at the meantime

[yinxing-ws]

for example, call method scrollTo with params {animated: true, duration: 10000}, and during the autoscroll time, user scroll will cause the flash.

expected: supply a way to disable user scroll or stop autoscroll when user scroll. such as return the timer and the scrollTop/scrollLeft value, so that user can stop the timer or prevent user scroll.
